display <-input_devices: -> chain

Chain of input_device objects known to xpce. It holds at least @mouse_device and @keyboard_device. Other devices are added when the window system reports them. The chain should not be modified.

When a device is added or removed, e.g., a gamepad is plugged in, the window with the keyboard focus of each frame receives a device_added or device_removed event, whose event<-device is the device.
